The Girl On The Train is out today in cinemas, starring Emily Blunt as a habitual commuter and alcoholic voyeur who becomes fatally involved with a family she watches from the train. Read our rather glowing review of the film. It's is adapted from Paula Hawkins' addictive bestseller, often described as "the next Gone Girl".

Paula says: "I think this would be visually amazing. It's about the incredibly intensely competitive world of gymnastics, of young women, teenage girls, who are potentially good enough to go to the Olympics. They live under this unbelievable pressure. There's a young man who works at their gym who is killed in a hit and run so that's the mystery. It's claustrophobic and slightly frenzied and there's the feeling that the fate of a whole place rests on the slender shoulders of a 13-year-old girl."

Paula says: "A young girl is murdered, there's a suspicion of sexual assault and the detective who's sent to investigate actually grew up near where it happens. Something horrible happened to him when he was a child that he can't remember; he was playing in the woods with friends and two of them disappeared and were never seen again and he has no memory of the incident, so it's all him trying to solve this and at the same time trying to unravel what this awful thing that happened to him in the woods was."

Paula says: "I think this is the only one of Gillian Flynn's that hasn't yet been adapted. Sharp Objects is about a really damaged young woman who returns to her hometown. She's working as a journalist and other young girls are being murdered, there's some sort of serial thing going on. It's a creepy setting and she has this really messed-up relationship with her mother. She'd be an interesting character, she's got tattoos all over herself, she was a cutter – I think it would feel very current."

Paula says: "It's slightly veering into gothic horror but the setting is amazing. The cast of characters is freaking weird and out of their time but also very believable. And there's this completely terrifying thing that's going on and half the time you just don't know what it is. There's a boy and his brother, who has a developmental disability, who go every year on a very strange pilgrimage to this unspecified marshy place called The Loney. One year they go strange things start happening and they encounter locals who are at first helpful and then become quite sinister and frightening very quickly."

Paula says: "I find it odd that no one's ever made this. There's a whole generation of people who loved that book, it's such a weird cast of characters, their strange intense relationships with each other, and, you know – Bacchanals. It's been described as a murder mystery in reverse because you know at the beginning what's happened. It's a close group of friends and one of them has been killed but it's unpicking what has gone wrong in all their relationships."

The Girl On The Train is in cinemas now, and you can read the book now (£12.99, Doubleday).
